Aging Eyes

I'm sure I'm not the only aging babyboomer out there who has trouble seeing the LCD details on his/her digital cam underwater. I've thought about some bi-focal type mask that would let me see the LCD more clearly yet not impair distance vision. Any good tips out there. I'm new to digital u/w and have just bought a Cannon G2 with Ike housing and DS 50 strobe. Thanks.
